the correct answer should be (b) 6 is extraneous.
If you look at the second row of the solution you see (x-6) as a factor in one of the denominators. That's a problem: if 6 were a solution this denominator would become 0. But denominators being 0 is bad (undefined), so while 6 comes out of the algebraic manipulation as a solution, it is invalid, or extraneous.
-3 is a fine solution.
Answer:
The original temperature was -18°F
Step-by-step explanation:
x°F + 24°F = 6°F
or, x°F = 6°F - 24°F
so, x°F = -18°F
Answer:
Step-by-step explanation:
Given
Point (4,-5)
Required
Determine the line equation
From the question, we understand that the line is parallel to
This implies that they have the same slope, m
A linear equation is:
Where
By comparison: and
Next, we determine the line equation using:
Where
and
Hence,
<em>Option C is correct</em>

Answer:
D. Y=-3/2x-3
Step-by-step explanation:
(0,-3)
-3=-2/3(0)+b
-3=b
y=-3/2x+3 parallel slope is -3/2
Y=-3/2x-3
